Description
Majin Duu is a character from the anime Dragon Ball Daima, introduced as a powerful Majin created by the witch Marba. He is the second and more formidable creation made to serve the ambitions of the scientist Dr. Arinsu, following the initial and weaker Majin Kuu.
In terms of background, Majin Duu was conceived after the failure of his predecessor, Majin Kuu, to defeat one of the Demon Realm's guardians, the Tamagami. To create a more powerful entity, Dr. Arinsu instructed Marba to use the last remaining Saibaman seed, planting it deeper in her special soil and infusing it with the remainder of the essence of the original Majin Buu that had been acquired from Earth. This process resulted in Duu, who physically resembles the innocent form of Majin Buu much more closely than his brother Kuu. He shares the same obese physique, antenna, and typical Majin outfit of baggy white pants and dark armbands. However, his color scheme is a green hue inherited from the Saibaman, and his eyes have black sclera with red pupils, giving him a more demonic appearance.
The personality of Majin Duu is heavily influenced by his genetic template, Majin Buu. He is defined above all else by a gluttonous love for sweets, particularly chocolate. Upon his creation, his first action is to loudly demand chocolate, and his mood and combat effectiveness are directly tied to his consumption of treats. When he is given a tasty snack, he enters a kind of sugar rush, becoming immensely more powerful and energetic. Conversely, if he is denied chocolate during a fight, he becomes demotivated, refuses to continue, and may even begin to wail. Beyond his obsession with food, Duu is childlike, dim-witted, and highly unpredictable in battle, using bizarre tactics and body manipulations that confound his opponents. He struggles with complex tasks like mental arithmetic, showing a lack of conventional intelligence, yet possesses an instinctual genius for combat.
His primary motivation is simple and driven by immediate desires: to eat sweets and to follow the orders of Dr. Arinsu, to whom he shows a basic level of obedience. This obedience may be a result of his Saibaman genetics. He also shares a strong, sibling-like bond with Majin Kuu, who looks after him. Kuu is often seen running errands for his younger brother, such as buying him chocolate, and the two work together effectively, with their shared love of sweets being a common interest.
In the story of Daima, Majin Duu serves as a major obstacle for the protagonists. He is unleashed to challenge Tamagami Number One and obtain a Dragon Ball for Dr. Arinsu. His chaotic fighting style and immense power allow him to overwhelm the guardian, especially after being fed chocolate by his brother. However, after winning the battle, he nearly fails the subsequent mental arithmetic challenge required to claim the Dragon Ball, only passing when Kuu covertly whispers the correct answers to him. Later, when the greater threat of the demon king Gomah, empowered by the Evil Third Eye, emerges, Majin Duu shifts from being an antagonist to an unlikely ally. He joins forces with Goku and the others in the final battle, following Bulma's request for Dr. Arinsu's help.
Key relationships define his role. He is a loyal, if simple-minded, subordinate to Dr. Arinsu, who values him for his power. His relationship with Majin Kuu is one of the most developed; Kuu is the caring elder brother who ensures Duu is fed and even helps him solve problems. During the final battle, Kuu provides him with a giant cookie, which triggers a significant power boost. He also develops a brief but notable rivalry and partnership with Goku, as the two fight side-by-side after Duu mimics the Super Saiyan 3 form.
Throughout the story, Majin Duu does not undergo a fundamental character change but rather finds his place. He begins as a newly created weapon and ends as a recognized member of the new Demon Realm leadership. After the main conflict is resolved and Gomah is sealed away, Majin Kuu becomes the new Supreme Demon King and selects Majin Duu to serve as one of his ministers, solidifying his role as a powerful and loyal ally within the new order.
His notable abilities are a direct reflection of his Majin heritage mixed with his unique nature. He possesses the standard Majin powers of flight and body manipulation, allowing him to stretch, contort, and reshape his form for attacks like the Mystic Ball Attack and Wrap Attack. A key skill is his Mimicry, the ability to copy a technique after seeing it only once. He uses this to learn how to fire ki blasts and, most dramatically, to mimic Goku's Super Saiyan 3 transformation after being given a special cookie. This Super Saiyan 3 Mimicry form grants him spiky, hair-like tentacles and a massive, though temporary, increase in power, allowing him to damage the empowered Gomah. His signature finishing move is a powerful energy wave fired from his mouth. His power level is high enough to defeat a Tamagami and briefly match Super Saiyan forms of Goku, though it is dependent on his sugar-induced power-ups and is ultimately below the might of the Third Eye-powered Gomah.
